A randomized controlled pilot study into the effects of a restricted elimination diet on family structure in families with ADHD and ODD.

BACKGROUND

Behavioural improvements of children with attention-deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) following a restricted elimination diet (RED), may be due to concurrent changes in family environment.

METHODS

Twenty-four children with ADHD, were randomized to either a 5-week RED intervention, or a control intervention consisting of healthy food advices in a pilot study.

RESULTS

No differences in family environment were found, neither at baseline nor when comparing the start and end measurements of both groups.

CONCLUSIONS

In this pilot study, the effects of an RED on ADHD and ODD are not mediated by improvement of family environment in families motivated to follow an RED. Replication of this preliminary study in larger groups of children is advised.
